Deviance-Related Responses along the Auditory Hierarchy: Combined FFR, MLR and MMN Evidence
Fig 1
Grand average power spectrum of FFR at CPz electrode yielding a maximum peak at the modulation frequency (410 Hz).
The waveforms are shown for reversed-standard (blue) and deviant (red) stimuli. The grey shaded bar denotes the window of the mean power used for statistics (405–415 Hz). The arrow on the x-axis indicates the modulation frequency (410 Hz). Note the significant enhancement of the spectral power at 410 Hz elicited by deviant stimuli (p < 0.05).
